Abstract
We examine the most recent literature concerning POEM since the last two comprehensive analyses [Natural Orifice Surgery Consortium for Assessment and Research (NOSCAR) White Paper, ASGE Preservation and Incorporation of Valuable endoscopic Innovations (PIVI)], and integrate this literature in the consensus POEM guidelines and perspective. These current works are largely centered on POEM operator learning curve, comparison of POEM and laparoscopic Heller myotomy (LHM) and extended application of POEM. POEM and LHM are comparable in terms of efficacy (diminished dysphagia and Eckardt score) and complications including GERD. POEM has been successfully performed in a wide variety of patients including children, those with prior achalasia therapy and those with spastic esophageal disorders. POEM has been validated as a treatment for achalasia. Issues remain regarding its longer term efficacy in comparison with LHM. Subsequent comparison trials are needed. http://links.lww.com/COG/A14.
